The Seiko SSB417P1 weighs 85 grams in a 43mm case, which is the number that defines it. A steel chronograph this size on a metal bracelet typically runs to 150 grams; pairing the case with a black nylon strap takes almost half of that away, and turns a large watch into one you can forget you are wearing.
The deep black dial carries the three counters characteristic of a chronograph, ringed by a tachymetre bezel finished in titanium carbide coating — a hard surface treatment that keeps the bezel looking sharp where it takes the most contact. A sapphire crystal protects the dial, LumiBrite is applied to the hands and indexes, and the case is closed with a screw case back and rated to 100 metres. Calibre 8T63 holds ±15 seconds per month and includes a 24-hour hand, running three years on a battery.

Why You'll Love It
- 85 grams at 43mm. That is the headline — a large chronograph that weighs less than most 40mm watches on a steel bracelet, because the nylon strap takes the weight out.
- Sapphire crystal, not mineral glass. Sapphire rates 9 on the Mohs hardness scale, so it resists the everyday scratches that dull a watch face over years of wear.
- The bezel is finished in titanium carbide coating — a hard surface treatment on the part of the watch that meets doorframes and desk edges first.
- A tachymetre on the bezel rather than printed on the dial, which keeps the dial itself clean and leaves the scale easier to read.
- ±15 seconds per month. Set it and forget it, where a mechanical chronograph would drift that much in a couple of days.
- Nylon suits this climate. It handles heat and humidity, dries quickly, and can be washed — none of which is true of leather.
- LumiBrite on the hands and indexes keeps a busy dial readable in the dark without any power draw.
- Three years from a battery, then a straightforward replacement. No winding, no charging, no routine.

Key Features
- Calibre 8T63 quartz chronograph movement — accurate to ±15 seconds per month, with three years from a battery.
- Three chronograph counters across a deep black dial, in the classic chronograph layout.
- 24-hour hand — a separate indication running on a 24-hour cycle, alongside the main time display.
- Tachymetre bezel — the scale sits on the bezel rather than the dial, for calculating speed over a measured distance.
- Titanium carbide coating on the bezel — a hard surface treatment applied where the watch takes the most contact.
- Sapphire crystal — rating 9 on the Mohs hardness scale, the harder of the two crystal materials Seiko uses at this level.
- Stainless steel case — 43.0mm across and 11.6mm thick, closed with a screw case back, at a total weight of 85 grams.
- LumiBrite on hands and indexes — Seiko's luminous compound charges under light and reads clearly in the dark without drawing any power.

Frequently Asked Questions
How can a 43mm chronograph weigh only 85 grams?
The strap. A steel case of this size on a matching steel bracelet typically comes to around 150 grams, and most of that weight is in the bracelet rather than the watch head. Pairing the same case with nylon removes it. The result is a large, legible chronograph that sits light enough to wear through a full day without noticing it.
What is the tachymetre bezel for?
It converts elapsed time into speed over a known distance. Start the chronograph as you pass a marker, stop it one kilometre later, and the number the chronograph hand points to on the bezel is your average speed in kilometres per hour. It works for any unit as long as the distance is one of them, and it only reads speeds fast enough to cover that distance in under a minute. Having the scale on the bezel rather than printed on the dial keeps the dial itself cleaner.
What does the titanium carbide coating do?
It is a hard surface treatment applied to the bezel, which is the part of a watch that meets doorframes, desk edges and bag straps first. The coating raises surface hardness so the bezel holds its finish through contact that would mark bare steel. It remains a surface treatment, so a hard enough impact against a sharp edge can still leave a mark.
How do I use the chronograph?
The upper pusher starts and stops the timing, and the lower pusher resets it to zero once stopped. Elapsed time is read from the three counters on the dial, while the main hands continue showing the time of day throughout.
What is the 24-hour hand for?
It runs on a 24-hour cycle rather than a 12-hour one, so it tells you at a glance whether the time shown is morning or evening. It is useful in low light, and for anyone who works to a 24-hour clock.
Is sapphire better than mineral glass?
For scratch resistance, yes. Sapphire rates 9 on the Mohs hardness scale, well above the Hardlex mineral glass Seiko fits to many chronographs at this level, so it keeps a clear face over years of daily wear. Mineral glass is the more shatter-resistant of the two under heavy impact, so it is a genuine trade rather than a straight upgrade — but for most owners, scratches are the wear you actually see.
How accurate is it?
±15 seconds per month, which is the figure Seiko quotes for this movement. In practice that means adjusting it once or twice a year rather than weekly.
How long does the battery last?
Three years. Running the chronograph frequently draws more power and can shorten that. When it needs replacing, bring it to any City Chain outlet rather than opening it yourself — the screw case back has to be resealed correctly or the watch loses its water resistance.
Can I swim with it?
Yes. At 100-metre water resistance it handles swimming and recreational water activity, and nylon dries far faster than leather. It is not a diver's watch and is not rated for scuba diving. Never operate the crown or the chronograph pushers while the watch is wet — that is the most common way water gets into a chronograph.
How do I look after the nylon strap?
Rinse it in fresh water after exposure to sweat, salt water or chlorine, and let it dry away from direct heat. Nylon is the most forgiving strap material there is — it will take a wash and keep going — and it is inexpensive to replace once it eventually wears.
Can I change the strap?
Yes. The lug width is 22mm, one of the most widely available sizes, so leather, rubber, mesh and steel bands all fit. Bear in mind that a steel bracelet would add considerable weight to a watch whose main quality is how light it is.
What warranty does this watch come with?
The SSB417P1 comes with a 3-year warranty when purchased from City Chain Singapore, an authorised Seiko retailer. Keep your warranty card and proof of purchase — both are required when submitting the watch for service.
